Ameasure of the ability to attract electrons in a chemical bond is electron positivity electronegativity ionization energy ionic

Option (b) is the correct answer.

Explanation:

When an atom is able to attract electrons towards itself then this ability of readily accepting an electron is known as electronegativity.

For example, atomic number of oxygen is 8 and its electronic distribution is 2, 6. So, in order to completely fill its orbital in order to gain stability it readily accepts two electrons.

Thus, we can conclude that a measure of the ability to attract electrons in a chemical bond is electronegativity.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
